Business-to-business (B2B) ecommerce company Udaan on Monday laid off 100 to 120 employees, about 10% of its workforce, days after raising $340 million in a funding round. Most of the job cuts happened in the go-to-market (GTM) team, which handles relationships with sellers, among other responsibilities, people in the know said. The layoffs, the sources explained, were due to redundancies following a rejig of the business in September.
